Reductive Ring㎡pening Reaction of 2,3〦poxy4‐butanediones with SbCl3〣u4NI in the Presence of Na2S2O3·5H2OShinsei Sayama
these two spectroscopic techniques are more frequently employed in isolation than in combination, owing to the assumption that they provide largely overlapping information regarding reaction intermediates
Starchsolution was added into the mixture. When the color changed from blue to colorless, the reactionwas complete. The following is the reaction:I2(aq)+2S2O-(aq)—→2I-(aq)+S4OVolume of Na2S2O3 beforeVolume of Na2S2O3 afterConcentration of Na2S2O3Trailtitration(mL)±0.05 mLtitration(mL)±...
The protecting group moiety may be chosen in such a way, that they are stable to certain reaction conditions and readily removed at a convenient stage using methodology known from the art. A non-limiting list of protecting groups include benzyl; substituted benzyl; alkylcarbonyls (e.g., t-...
The reaction between Fe(VI) and SRHA decreased the DOC in water by 23.3% (Table SM-4). This amount of DOC could be removed from the dissolved phase as aggregates, due to the coagulation effect of Fe(VI), or converted to inorganic C due to the oxidation by Fe(VI) (Dong et al.,...
The reaction vessel was flushed thoroughly with N2 and then heated in an oil bath set at 80 ◦C. Heating was continued for 1 h and then the mixture was allowed to cool. Evaporation of the solvent and flash chromatography of the residue over 10% KF–silica gel52 (1.5 × 30 cm), ...
